In order to improve the air quality of Tainan City, the “Constructional Activities Control and Air Quality Management Project” was being executed by us (Excellent State Tech. Co., LTD) according to the demand of the Tainan City EPB. The achievements of the project have been summarized as follows: 1. Background data analysis The average population growth rate of Tainan City from 1991 to 2006 is 0.64% which had grown gradually and stably. The number of motor vehicles had increased dramatically since 1998 until 2006 whose average growth rate is 2.97%. The number of plants had decreased form 3,405 sites in 1991 to 2,546 sites in 2006, the average reduction rate is 1.74%. According to accumulated data of the days and sites whose PSI>100 from Jan. to Dec. 2006, most of PSI>100 days was caused by ozone (33 site-days for ozone and 21 site-days for PM10). The major PSI>100 days was 7 site-days increased of PM10 in Mar., and 21 site-days increased of ozone and 7 site-days increased of PM10 during Sep. to Nov.. 2. Air pollutants composite structure of different sources The result of the comparison of the quantity of air pollutants from 2002 to 2006 reveals that the air pollutants generated by mobile sources accounts for the major proportion of Tainan City’s total air pollution. The City has been promoting the “Anti-idling activity” for motor vehicles since 2006 so as to control air pollutants of mobile sources. 3. Announcement for inferior air pollution by air quality forecast and reaction SOP The accuracy of the EPA forecasts for PSI>100 is about 25.42% per day. The accuracy of forecast for ozone is 23.52% and 22% for PM10. 4. Continue to improve Air Pollution Control Plan of Tainan City This project is to draw up the air pollution control strategy according to the experiences of every sub-project as well as the characteristics of Tainan City; the short-term control strategic period was set to be 2006 to 2007, the med-term control strategic time is 2009 and the long-run is the year 2014. 5. Others This project has been mainly supervised by the EPA and the Tainan City EPB, the supervisory group is composed of scholars and specialists from environment, landscape and horticulture as well as the management of Tainan City EPB. This project had done several satisfaction survey including the citizen and organization’s satisfaction on the administration. The 67.7% of Stationary Sources Discharge Permit applicants showed the satisfaction on the efficiency of permit examination and grant, and the 65.8% of Stationary Sources Discharge Permit applicants showed the satisfaction on the profession of on-site inspectors.
